我正在尝试创建一个包含 10 个图像的 pdf。所有这 10 张图像都可以使用下面的这种方法直接从数据库中检索出来。
这是我用来创建 PdfPTable 以在其中插入数据的代码。
protected void btnPDF_Click(object sender, EventArgs e)
{
var doc1 = new Document();
var filename = "MyTestPDF" + DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".pdf";
var output = new FileStream(Path.Combine("C:\\Users\\apr13mpsip\\Downloads", filename), FileMode.Create);
iTextSharp.text.pdf.PdfWriter.GetInstance(doc1, output);
doc1.Open();
PdfPTable table = new PdfPTable(1);
table.TotalWidth = 585f;
table.LockedWidth = true;
PdfPTable table2 = new PdfPTable(1);
table2.TotalWidth = 585f;
table2.LockedWidth = true;
iTextSharp.text.pdf.PdfPCell imgCell1 = new iTextSharp.text.pdf.PdfPCell();
var logo = iTextSharp.text.Image.GetInstance(Server.MapPath("~/image/logo.jpg"));
doc1.Add(logo);
var titleFont = FontFactory.GetFont("Arial", 15, Font.BOLD);
doc1.Add(new Paragraph("Official Report. Member Report ID : " + DDLCase.SelectedValue, titleFont));
var normalFont = FontFactory.GetFont(FontFactory.HELVETICA, 14, Font.BOLD);
var phrase = new Phrase();
var phrase2 = new Phrase();
这是我的数据库连接代码，我将我的 SQL 服务器数据库与我的项目链接起来。
SqlConnection con = new SqlConnection("Data Source = localhost; Initial Catalog = project; Integrated Security = SSPI");
SqlCommand cm = new SqlCommand("Select lro.fullname, lro.contact, mr.typeofcrime, mr.location,mr.crdatetime, mr.citizenreport, pr.policeid, pr.prdatetime, pr.policereport, aor.officialreport, mr.image1, mr.image2, mr.image3, mr.image4, mr.image5, pr.image1, pr.image2, pr.image3, pr.image4, pr.image5 from MemberReport mr, PoliceReport pr, LoginRegisterOthers lro, AdminOfficialReport aor where mr.memberreportid = '" + DDLCase.SelectedValue + "' and mr.memberreportid=pr.memberreportid and pr.policereportid=aor.policereportid", con);
con.Open();
SqlDataReader dr;
dr = cm.ExecuteReader();
这就是我使用 datareader 读取 SQL 服务器中的数据并检索将生成并显示到 PDF 中的相应图像和信息的方式。
if (dr.Read())

phrase.Add(new Chunk("Full Name :", normalFont));

我也有一个PdfPTable只有一列的单元格，我无法添加单元格以将特定图像分配到特定单元格中。
如您所见，我直接从我的 SQL 数据库中检索我的图像，因此我相信将图像添加到相应的单元格中会更加困难。
这是我发布的关于我发布的线程的一些链接1和链接2 ，它们都有图片对齐问题。上面提供的链接都有显示大对齐问题的图片。因此，我能想到的正确对齐图片的唯一方法是添加一个单元格并将图像放入相应的单元格中。我希望有相同大小的并排对齐的图片。
